ABSTRACT

A new and distinct Guzmania hybrid named ‘FUSION’ characterized by solid growth habit; funnel-form rosette plant, measuring about 42 cm to 48 cm in height (above the pot when flowering); numerous, dark green color foliage, measuring about 30 cm to 35 cm in length and about 3.0 cm to 4.0 cm in width; superior floral bract production; bracts have a unique dark purple color which distinguishes this cultivar from typical Guzmania; round, compound inflorescence, measuring about 30 cm in height and about 18 cm in diameter; and long-lasting habit.

FIELD OF THE INVENTION

The present invention relates to a new, distinct and stable hybrid ofGuzmania hybrid, hereinafter referred to as ‘FUSION’. The presentinvention relates to seeds which are the Guzmania hybrid ‘FUSION’, aswell as, plants and plant parts produced by these seeds which have allof the morphological and physiological characteristics of the Guzmaniahybrid ‘FUSION’. The present invention also relates to methods forproducing these seeds and plants of the Guzmania hybrid ‘FUSION’.Furthermore, the present invention relates to a method of producingprogeny Guzmania plants by crossing Guzmania‘FUSION’, as either thefemale or seed or male or pollen parent, with another Guzmania plant andselecting progeny.

BACKGROUND OF THE INVENTION

The present invention relates to a new, distinct and stable hybrid ofGuzmania hybrid, and hereinafter referred to by the variety denomination‘FUSION’. The new Guzmania ‘FUSION’ originated from a cross made in acontrolled breeding program by the inventors in 2002, and then firstflowered in 2005, in Assendelft, The Netherlands. The female or seedparent is the Guzmania wittmackii inbred line identified by code0215793002 (unpatented). The male or pollen parent is the Guzmanialingulata flammea inbred line identified by code 0215706 (unpatented).

Guzmania is a member of the Bromeliaceae family. Guzmania ispredominantly epiphytic with a few terrestrial species and is native tothe tropics. For the most part, species vary in diameter from 7 or 8inches to 3 or 4 feet and have rosettes of FUSION, smooth-edged leaves.

Floral bracts of Guzmania frequently have brilliant colors and may lastfor many months. The range of colors for Guzmania is generally fromyellow through orange but may also include flame red and red-purple.White or yellow, tubular, three-petalled flowers may also appear on astem or within the leaf rosette but are usually short-lived.

Guzmania may be advantageously grown as pot plants for greenhouse orhome use. Typically, the plants are shaded from direct sunlight. Duringthe spring to autumn period, the central vase-like part of the leafrosette is normally filled with water.

Guzmania is native to tropical America. Leaves of Guzmania are usuallyformed as basal rosettes which are stiff and entire and in severalvertical ranks. Guzmania plants have terminal spikes or panicles whichare often bracted with petals united in a tube about as long as thecalyx. The ovary is superior and the seeds plumose.

Asexual propagation of Guzmania is frequently performed by vegetativemeans through the use of tissue culture practices. Propagation ofGuzmania can also be from offshoots which can be detached from themother plant and grown in an appropriate soil or bark mixture.

Methods for cultivation and crossing of Guzmania are well known. For adetailed discussion, reference is made to the following publications,which are incorporated herein by reference: Benzing, David H., THEBIOLOGY OF THE BROMELIADS, Mad River Press, Inc., Eureka (1980); Zimmer,Karl, BROMELIEN, Verlag, Paul Parey, Berlin (1986); and Rauh, Werner,BROMELIEN, Verlag Eugen Ulmer, Stuttgart (1981).

A Guzmania inbred is produced by brother/sister crossing over severalgenerations to produce a genetically homozygous plant selection. Ahybrid cultivar is produced by crossing two genetically distinct inbredlines, collecting seeds produced by the cross, and germinating seedsso-produced to make hybrid plants. The hybrid seeds and plants producedby this method are uniform with respect their morphological andphysiological characteristics.

A need exists for a greater variety of Guzmania cultivars withattractive ornamental features. Additionally, a need exists foradditional Guzmania hybrid cultivars that can be easily propagated byseed. The new Guzmania ‘FUSION’ was developed through a controlledbreeding program and exhibits unique, desirable and stablecharacteristics.

SUMMARY OF THE INVENTION

The present invention provides Guzmania plant selections that are solid,medium-sized, long-lasting hybrids with superior bract production anddark purple inflorescence that exhibits good keeping quality. Thepresent invention also provides Guzmania plant selections with acompound inflorescence with a unique dark purple color whichdistinguishes the new cultivar from typical Guzmania.

These and other objectives have been achieved in accordance with thepresent invention which provides ‘FUSION’ as a new Guzmania cultivarthat is a product of a planned breeding program conducted by theinventors, Elly Bak and Nico D. M. Steur, in Assendelft, TheNetherlands, in 2002. The female or seed parent is the Guzmaniawittmackii inbred line identified by code 0215793002 (unpatented). Themale or pollen parent is the Guzmania lingulata flammea inbred lineidentified by code 0215706 (unpatented).

Both parental cultivars have a sufficient degree of homozygosity suchthat the progeny of the cross are genetypically and phenotypicallyuniform. The new hybrid ‘FUSION’ therefore can be produced by sexualreproduction by crossing the parental inbred lines identified by thecodes 0215793002 and 0215706 to produce a population of progeny plants,each of which has the combination of characteristics as herein disclosedfor the new hybrid ‘FUSION’.

Seeds which are the hybrid ‘FUSION’ are produced by crossing theparental inbred lines identified by the codes 0215793002 and 0215706,and are deposited with the American Type Culture Collection, 10801University Boulevard, Manassas, Va. 20110-2209. ATCC Patent DepositDesignation No. PTA-8832. 2500 seeds were deposited with the ATCC onDec. 3, 2007.

DETAILED BOTANICAL DESCRIPTION

The present invention was created by the inventors, Elly Bak andNicolaas D. M. Steur in 2002, and flowered for the first time in 2005 inAssendelft, The Netherlands.

This invention is directed to Guzmania plant having all themorphological and physiological characteristics of the hybrid ‘FUSION’produced from seeds which are the product of the cross of the Guzmaniawittmackii inbred line identified by code 0215793002 (unpatented) as thefemale or seed parent with the Guzmania lingulata flammea inbred lineidentified by code 0215706 (unpatented) as the male or pollen parent.Both parents have a sufficient degree of homozygosity such that theprogeny of the cross were, and continue to be, phenotypically uniform.The new hybrid ‘FUSION’ can therefore be produced by sexual reproductionby crossing of the inbred selections identified by the codes 0215793002and 0215706 to produce a population of progeny plants, each of which hasthe combination of characteristics herein disclosed for the new hybrid‘FUSION’.

The new hybrid ‘FUSION’ can also be produced by asexually reproducingprogeny from the cross of the parental inbred lines identified by thecodes 0215793002 and 0215706. Asexual reproduction of the new cultivarby vegetative means by cuttings was first performed in 2005, inAssendelft, The Netherlands. The first ‘FUSION’ plants propagatedthrough the use of such cuttings flowered in 2007, in Assendelft, TheNetherlands, and have demonstrated that the new cultivar reproducestrue-to-type and that the combination of characteristics as hereindisclosed for the new cultivar are firmly fixed and retained throughsuccessive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe unique characteristics of ‘FUSION’ which in combination distinguishthis Guzmania as a new and distinct cultivar:

-   -   1. Solid growth habit;    -   2. Funnel-form rosette plant, measuring about 42 cm to 48 cm in        height (above the pot when flowering);    -   3. Numerous, dark green color foliage, measuring about 30 cm to        35 cm in length and about 3.0 cm to 4.0 cm in width;    -   4. Superior floral bract production;    -   5. Bracts have a unique dark purple color which distinguishes        this cultivar from typical Guzmania;    -   6. Round, compound inflorescence, measuring about 30 cm in        height and about 18 cm in diameter; and    -   7. Long-lasting habit.

Plants of the parental lines, 0215793002 and 0215706 (both unpatented)are no longer available to provide a detailed botanical comparison withthe new Guzmania hybrid ‘FUSION’

Of the many commercial cultivars known to the present inventors, themost similar in comparison to the new Guzmania hybrid ‘FUSION’ is theGuzmania cultivar ‘FIESTA’ (unpatented). Plants of the new hybrid‘FUSION’ differ from plants of ‘FIESTA’ primarily in inflorescencecolor. Plants of ‘FUSION’ produce inflorescence which are dark purplewhereas plants of ‘FIESTA’ produce inflorescence which are red.

‘FUSION’ has not been tested and observed under all possibleenvironmental conditions. The phenotype of the new cultivar may varywith variations in environment such as temperature, light intensity,frequency of fertilization, composition of fertilizer, acetylenetreatment, day length and humidity, without any change in the genotypeof the plant.

For example, substantial differences in plant height and diameter,number of leaves, can result depending on the size of the plant at thetime that flowering is induced by acetylene treatment. Since treatmentwith acetylene to induce flowering disrupts normal watering andfertilization regimens, acetylene treatment of relatively smaller plantsadversely affects the growth of the plant.

The aforementioned photographs, together with the followingobservations, measurements and values describe the new Guzmania ‘FUSION’as grown in a greenhouse in Assendelft, The Netherlands, underconditions which closely approximate those generally used in commercialpractice. Plants of ‘FUSION’ were grown in a greenhouse with daytemperatures ranging from 20° C. to 28° C. and night temperaturesranging from 18° C. to 23° C. No artificial lighting or photoperiodictreatments were conducted, but plants of ‘FUSION’ are forced intoflowering by adding acetylene. The following fertilizer is added whengrowing plants of ‘FUSION’: 1 part nitrogen, 0.6 parts phosphor, 2 partsKalium and 0.1 parts magnesium.

Color references are made to the Royal Horticultural Society ColourChart (RHS), 2001 edition, except where general colors of ordinarysignificance are used. Color values were taken under daylight conditionsin a greenhouse in Assendelft, The Netherlands. The age of the plants of‘FUSION’ described is about 10 weeks after treatment with acetylene.
